Explanation:
A tall pea plant (Tt) is crossbred with another tall pea plant (Tt). The following Punnett square shows the separated alleles for two pea plants.
Which of the following shows the correct match of the box numbers and the genotype of the offspring?
Btw graph is below (ScreenShot)
Answer:
B.
Explanation:
when you use punnett squares, you cross the different genes with themselves. if T is in the first box on both sides, the genome will be TT. if the box lines up to tt, it will be tt. the boxes on the left use the genes' first letter and the boxes on the right use the second letter.
The result of the cross between Tt and Tt would be TT, Tt, Tt, tt.
Monohybrid crossingThis is a kind of crossing involving only one trait.
The genotype Tt will segregate to T and t respectively.
Crossing Tt and Tt:
Tt x Tt
TT Tt Tt tt
Thus, box 1 will contain TT, box 2 will contain Tt, box 3 will contain Tt, and box 4 will contain tt.

During autumn, what happens? (Select all that apply.)
Days become warmer and longer.
Animals prepare to survive the winter.
Some trees begin to shed their leaves.
Plants prepare to survive the winter.
During autumn, several changes occur in nature. Some of the changes that happen during this season include:Days become cooler and shorter,animals prepare to survive the winter.some trees begin to shed their leaves and plants prepare to survive winter, thus all options are correct.
1. Days become cooler and shorter: As autumn arrives, the weather gradually becomes cooler. The days also become shorter, meaning there is less sunlight each day. This decrease in daylight hours is due to the Earth's tilt on its axis as it orbits the sun.
2. Animals prepare to survive the winter: Many animals start making preparations for the upcoming winter during autumn. They may begin to store food or find sheltered places to hibernate. For example, squirrels gather and store nuts, birds migrate to warmer regions, and bears build up fat reserves for hibernation.
3. Some trees begin to shed their leaves: One of the most notable changes during autumn is the colorful transformation of tree leaves. Some trees, such as deciduous trees, shed their leaves during this season. As the days shorten and temperatures drop, the trees receive less sunlight, which triggers the production of a pigment called anthocyanin. This pigment gives leaves their vibrant red, orange, and yellow colors before they eventually fall off.
4. Plants prepare to survive the winter: Just like animals, plants also make preparations to survive the harsh conditions of winter. They may enter a state of dormancy or store energy and nutrients in their roots to survive until spring. Some plants produce seeds or fruits during autumn, ensuring their offspring can grow when conditions become favorable again.
In summary, during autumn, days become cooler and shorter, animals prepare for winter, some trees shed their leaves, and plants make preparations to survive until spring. These changes are part of the natural cycle of life and adaptation to seasonal variations.Thus, all options are correct.

a train moving at a velocity of 15 m/s is accelerated to 24 m/s over a 12 second period
Answer:
o.75
Explanation:
A train moving at a velocity of 15 m/s is accelerated to 24m/s over a 12 second period, time traveled by the train is 12 seconds.
The initial velocity u of the train is 15 m/s, the final velocity v is 24 m/s, and the time t is 12 seconds. The train is undergoing uniform acceleration.
We can use the kinematic equation to relate the initial velocity, final velocity, acceleration, and time:
v = u + at
Solving for t:
[tex]\[ t = \dfrac{v - u}{a} \][/tex]
Given that a is the acceleration and is calculated as:
[tex]\[ a = \dfrac{v - u}{t} \][/tex]
Substitute the given values:
[tex]\[ a = \dfrac{24 \, \text{m/s} - 15 \, \text{m/s}}{12 \, \text{s}} \][/tex]
[tex]\[ a = \dfrac{9 \, \text{m/s}}{12 \, \text{s}} \\\\= 0.75 \, \text{m/s}^2 \][/tex]
Now substitute the calculated acceleration back into the equation for \( t \):
[tex]\[ t = \dfrac{v - u}{a} \\\\= \dfrac{24 \, \text{m/s} - 15 \, \text{m/s}}{0.75 \, \text{m/s}^2} \][/tex]
[tex]\[ t = \dfrac{9 \, \text{m/s}}{0.75 \, \text{m/s}^2} \\\\= 12 \, \text{s} \][/tex]
Thus, the time traveled by the train is 12 seconds.

Calculate the mass of an object that has a density of 20 g/mL and a volume of 5 mL.
Answer:
4
Explanation:
density= mass/volume
Answer:
100kg
Explanation:
[tex]density= mass/volume[/tex]
using this formula you can re arrange the equation my moving the volume onto the opposite side
giving you this formula : mass= density x volume
in doing so you can calculate the mass of the object by extracting the relevant information of the question
density=20g/ml
volume=5ml
mass = density x volume
=20 x 5
= 100
How do atoms and molecules of elements and compounds combine in chemical reactions?
Pls help it is due in 20 mins
Answer:
A compound is a unique substance that forms when two or more elements combine chemically. Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds. A chemical bond is a force of attraction between atoms or ions that share or transfer valence electrons
Answer:
Explanation:
When 2 or more elements combine a compound stats to form. These are held together with a very strong chemical bond (which can vary depends on the elements). This chemical bond makes all of these little ions come to it and thats how a chemical reaction is made.
